Just booted up the system (10.6.3), and got a prompt that a file is trying to access the internet. I don't remember installing anything new on this system yesterday, so I'm not sure what's going on. Its name is rsmac_3696, and here's the info for it:
I've checked the directory, and it contained the files I've posted below. I'm thinking it could have something to do with the Adobe CS5 trial that I got off of Adobe's site about five days ago (maybe these are the download manager files?
There's also a readme file which contains the following at the beginning:

Overview
-----------
This file describes the Akamai NetSession Interface.
The Akamai NetSession Interface runs as a service to manage downloads and to
let you manage the download process. It was installed on your computer when you
downloaded content that uses the service to provide secure, high integrity
downloads of large files.
The NetSession Interface supports downloading from a central source and between
peers. When peer-downloading is enabled, your computer can serve as an upload
source for other computers -- without adverse impacts to your computing.
Peer-to-peer downloading can provide faster, more effective downloads.
The NetSession Interface contains no adware or spyware, is safe and secure,
uses minimal resources, and provides you the ability to manage and control its
actions, including the ability to uninstall it if you do not want it on your
computer.
-----------------
How It Works
-----------------
The NetSession Interface does not have a noticeable desktop presence during
downloads, since its work is integrated into the sites or applications that use
the service.
However, there are two interfaces you can use to manage downloads and the
interface itself: AdminTool and a Control Panel extension.
